This is a fallout of my fix for PR ada/83016, which allowed the --LINK option 
of gnatlink to contain switches in addition to the linker itself.  There is a 
conflict with the switches passed with the --GCC option so this patch arranges 
for the former switches to take precedence over the latter switches when it 
comes to the final linking step.

Tested on x86-64/Linux, applied on the mainline.

	* gnatlink.adb (Process_Args): Drop existing link switches if multiple
	switches are passed for --LINK.
